Joseph James DeAngelo Jr., known as the Golden State Killer, pleaded guilty Monday to more than a dozen murders. Now the serial killer's exbrotherinlaw, James Huddle, is speaking out. Huddle told Inside Edition that the family had no idea about DeAngelo's crimes, though looking back, there were telltale signs that something wasn't right, including DeAngelo's interest in slasher movies such as "The Texas Chain Saw Massacre." #InsideEdition
